Welcome to the One Synth Challenge #134! It's a friendly music competition where you can win cool prizes but most importantly, meet amazing musicians, and learn a lot about mixing, sound design, and more!

Special Rule: You may use any one one synth, commercial or freeware. Commercial FX are ALLOWED. All submissions must include an element of synthesised bird-song!

Indaba - Has a mix of popular and indie artists with various contests like remixing and song writing.

Mix Challenge - Who can mix a song the best (Without adding extra recordings /musical additions)? Each person starts out with the same stems. Also includes other competitions, like the Song Writing Competition.

Wow, a very interesting set of spring OSC rules! I didn't understand the translation a bit, so I want to ask:
1) Did I understand correctly: my track should contain some (any) number of sounds similar to bird chirping, for example as an element of percussion, melodic line or atmosphere?
2) I don't have any one commercial VST, but to understand the rules, I want to ask: are commercial effects also subject to General conditions about the types of effects?
